1. A support structure for a flexible display module, comprising:
a plurality of brackets sequentially arranged in a first direction, the plurality of brackets each extending in a second direction, the second direction intersecting the first direction;
at least one connecting assembly, a connecting assembly of the at least one connecting assembly being connected to two adjacent brackets of the plurality of brackets, so that the two adjacent brackets are capable of rotating with each other in a set plane; the set plane being perpendicular to the second direction, wherein
the connecting assembly is configured to limit an included angle formed between the two adjacent brackets to be within a range of a first angle to a second angle, inclusive;
support surfaces of the plurality of brackets are capable of supporting the flexible display module; in a case where the included angle formed between the two adjacent brackets is at the first angle, the support surfaces of the plurality of brackets are capable of limiting a display surface of the flexible display module to be a flat surface; and in a case where the included angle formed between the two adjacent brackets is at the second angle, the support surfaces of the plurality of brackets are capable of limiting the display surface of the flexible display module to be a curved surface;
the plurality of brackets each include a main body structure and a connecting structure extending from the main body structure to a side of the main body structure away from the support surfaces; and
the connecting assembly is connected to connecting structures of the two adjacent brackets, wherein
the connecting structure includes a first connecting portion and a second connecting portion connected to each other, and the first connecting portion and the second connecting portion are arranged in a misaligned manner in the first direction;
the first connecting portion is used for connecting a second connecting portion in one bracket adjacent thereto, and the second connecting portion is used for connecting to a first connecting portion in another bracket adjacent thereto; and
the first connecting portion includes a first contact portion and a second contact portion extending from the first contact portion to a side of the first contact portion away from the support surfaces: a dimension of a portion of the second contact portion in the first direction is inversely proportional to a distance between the portion of the second contact portion and the first contact portion.
